Description

EXTENDED FINGER FLANGE FOR SYRINGE SYSTEMS
CROSS-RELATIONSHIP TO PENDING APPLICATIONS
[001] This application claims priority to provisional application Serial No. 61/331,752 filed May 5, 2010, which is incorporated herein by reference.
FIELD
[002] The embodiments provided herein relate generally to syringe systems for administering therapeutic agents to patients. More specifically, the embodiments relate to an extended finger flange that can be coupled to a syringe system to facilitate use.
BACKGROUND
[003] Because of the risk of communicable diseases, a number of syringes and adapters have been developed that are intended to prevent accidental needle sticks and/or inadvertent reuse of a syringe. The syringe safety systems come in a variety of forms. One form of a syringe safety system uses a needle guard comprising a body and an extendable shield. The shield can be manually or passively transitioned from a first, retracted position to a second, extended position following administration of the medicine within the syringe. In the extended position, the shield covers the needle, thereby protecting the user from accidental needle sticks.
[004] In use, the syringe system is typically held by a user with two or more fingers engaging a finger grip of the syringe system and the user's thumb disposed on a thumb pad or top surface of the syringe's plunger. In many present systems, the finger grip area is quite small resulting in a device that may be difficult to manipulate and control, especially for end users with joint pain or limited dexterity.
[005] Accordingly, an improved finger grip area for use with safety syringe systems would be useful.
SUMMARY
[006] The embodiments presented herein are directed to an extended finger flange that can be coupled with a safety syringe system to facilitate the use of the syringe. The finger flange comprises lateral surfaces which increase the surface area available for the end user's fingers. The extended area makes it easier for the end user to grip the device and administer an injection.
[007] The extended finger flange is a component that can be removably coupled with the syringe or syringe safety system. The extended finger flange can be press fit into place and/or it may include snap features which mate with one or more features on the syringe or syringe system to secure the extended finger flange into the desired location.

DETAILED DESCRIPTION
[016] Turning to the figures, Figure 1 depicts an exemplary embodiment of a syringe system 5 that can be used with the extended finger flange 10 of the present disclosure. As depicted, the syringe systems 5 includes a needle guard 40 configured to receive a syringe 20 having a plunger 30. The syringe 20 has a substantially smooth-walled cylindrical barrel 22, a hub or distal end 24 that is the administration end, and a proximal end 26. The proximal end 26 of the barrel 22 is configured to receive the plunger 30. The plunger 30 comprises a stem 32 and a radial portion or thumb pad 36. The distal end 24 of the cylindrical barrel 22 preferably comprises a needle port or luer fitting. Preferably, the needle of the syringe 20 is covered with a cap 25 prior to the attachment of the extended finger flange and/or administration of the medication.
[017] The syringe 20 is preferably housed inside the needle guard 40. Although the extended finger flange 10 of the present disclosure may be used with a variety of needle guards or directly with a syringe, in an exemplary embodiment the needle guard 40 comprises a body 50 for receiving and holding the syringe 20 and a shield 60 slidably attached to the body 50.
[018] In one exemplary embodiment, the shield 60 is a tubular member adapted to slidably fit on the body 50 and has a proximal end 62 and a distal end 64. The shield 60 comprises a pair of finger flanges 66. The distal surfaces 67 of the finger flanges 66 typically provide only a small surface area for the end user's fingers to grip and secure the syringe system.
[019] The shield 60 can include one or more trigger fingers 68 that extend proximally from the proximal end 62 of the shield 60. During administration of the medication, the radial portion 36 of the plunger 30 contacts the trigger fingers 68. This action allows the shield 60 to transition from a first, retracted position to a second, extended position to cover the needle. The needle guard 40 can also include a spring mechanism coupled to the body 50 and the shield 60 for biasing the shield 60 towards an extended position when the trigger fingers 68 are deflected radially.
[020] In an exemplary embodiment, the extended finger flange device 10 fits onto the needle guard 40 of the syringe system 5. The lateral flaps 12 of the extended finger flange 10 increase the surface area and make it easier for the end user to grip the device and administer an injection. The addition of the extended finger flange 10 makes it easier for end users that have joint pain or limited dexterity to handle and grip the device when they self-administer an injection by extending the area that they have to grip.
[021] The exact dimensions, orientation, and configuration of the lateral flaps 12 of the extended finger flange 10 can be varied to fit the requirements of the patient population served by the drug medication. For example, as shown in Figure 2, the lateral flaps 12 can comprise a wide, rounded area or the lateral flaps 12 can comprise a more rectangular shape as shown in Figure 4. As another example, as shown in Figure 3, the finger flaps 12 can have a downward orientation to further assist the end user in holding the device. The extended finger flange 10 is generally molded from plastic, such as, polypropylene, k-resin, or polycarbonate, or the like. Alternatively, the extended finger flange 10 can be manufactured using an over molded process (Figure 4). In this embodiment, a soft durometer elastomare could be molded over a ridged core to provide support to the device and a soft spongy feel to the user that would give a better grip and reduce the pressure on the user's fingers.
[022] As shown in Figure 3, the extended finger flange 10 is placed onto the outside of the needle guard 40 of the syringe system 5. The extended finger flange 10 can be coupled with the syringe system 5 in a variety of ways. As one example, the extended finger flange 10 can be coupled to the syringe system 5 using a slight press fit over the needle guard 40. In another embodiment, the extended finger flange 10 can be coupled to the syringe system 5 through a positive snap feature 14 (Figure 2) that couples the extended finger flange 10 and the syringe system 5 together. In this embodiment, the extended finger flange 10 comprises one or more snap features 14 that are configured to engage complimentary portions of the shield 60 of the needle guard 40. For example, the snap features 14 on the extended finger flange 10 can be configured to engage the lateral ends 63 (Figure 1) of the finger flange 66 on the shield 60.
[023] In an alternative embodiment shown in Figure 5, the extended finger flange 10 can be configured to slide on to the safety system 5 from the side. In this embodiment, the central portion of the extended finger flange 10 comprises a "C" shape. Attaching the extended finger flange 10 from the side reduces the chance of damaging the needle when attaching the extended finger flange 10 to the syringe system 5. In this embodiment, the extended finger flange 10 can be held in place by, for example, two upper snap features 18 and two side snap features 19. The snap features 18, 19 can engage complimentary portions of the shield 60. For example, the side snap features 19 can interact with recesses 65 on the shield 60, and the upper snap features 18 can interact with the lateral ends 63 of the finger flange 66 of the shield 60.
[024] In yet another exemplary embodiment, as shown in Figure 6, the extended finger flange 10 comprises one or more internal snaps 17 that press fit against the finger flange 66 of the shield 60 when the extended finger flange 10 is fully inserted onto the needle guard 40. Once fully inserted (see Figure 7), the snap features 17 press against the lateral edges of the finger flange 66 but not against the lateral ends 63 and, thus, does not apply pressure against the sidewall of the device. This
configuration prevents the extended finger flange 10 from deforming the needle guard 40. Such deformation could cause an increase in friction between the shield 60 and body 50 of the needle guard 40 and possibly prevent the shield 60 from extending relative to the body when activated.
[025] While the invention is susceptible to various modifications, and alternative forms, specific examples thereof have been shown in the drawings and herein described in detail. It should be understood, however, that the invention is not to be limited to the particular forms or methods disclosed, but to the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the appended claims.
